New Defender's Study Bible Notes
9:7 tetrarch. See note on Luke 3:19.
9:7 John. Note the esteem and awe in which Herod held John the Baptist. Although John had done no miracles himself (John 10:41), when Herod heard of the many miracles done by Jesus and His disciples, he immediately thought of John, even seriously considering the possibility that he had risen from the dead! His conscience evidently was burdening him with the enormous guilt of his crime in executing John.
